| 摘 要： | 研究采用离合器-离合器换挡方式的液力变速箱的换挡过程.以dSPACE为硬件平台,建立基于模型的自动变速箱数据采集系统,实现了对全电液自动变速箱控制信号和各状态参量的同步采集,描述了换挡过程中各参数对换挡的影响.试验结果表明,换挡过程中初始放油占空比与其变化率影响扭矩相过程中传递的扭矩,而初始充油占空比决定了惯性相时间的长短.

| Abstract: | Studies the hydraulic automatic transmisson and shift process with model based data acquisition system.Using dSPACE,a model based data acquisition system has been developed,that can collect control signals and state parameters of hydraulic automatic transmission real-time in the shifting process.The evaluation of the relationship among parameters during the shift process can be much more direct.Test results showed that the shift torque is affected by the initial off-going duty while the off-going duty slop in the torque phase,while the stage of inertia phase is influenced by the initial oncoming duty. |
